Hydro’s bauxite and alumina operations in Brazil have been successfully recertified by the Aluminum Stewardship Initiative (ASI) against its Performance Standard and Chain of Custody Standard, with certificates valid until 2025.

To obtain ASI certification, an independent audit verifies that the plants operate in accordance with defined standards related to governance, policy and management, transparency, environment and biodiversity, social issues and labor rights, among other aspects evaluated. DNV GL carried out audits of the bauxite and alumina operations in February this year.

The audit visited the Tailings Dry Backfill, a methodology for storing dry bauxite tailings, implemented in a pioneering way at Hydro Paragominas, and evaluated the work at the Solid Residues Deposit (DRSs), at the Hydro Alunorte refinery in Barcarena (PA), which has with the most modern and sustainable technology, available in the world, for bauxite waste deposits. The technicians also talked to neighboring communities and verified other activities carried out by Hydro in the region. “This certification reinforces our commitment to operating to the highest industry standards of responsibility and sustainability. With ASI in both standards (Performance and Chain of Custody), we provide the market with more choice for responsibly produced aluminum”, comments Carlos Neves, Hydro's Director of Bauxite & Alumina Operations.

The Aluminum Stewardship Initiative (ASI) is a non-profit, global certification and standards-setting organization that brings together companies, users and all stakeholders in the aluminum value chain with a commitment to driving sustainability in the production process.
